A neat looking seeedling, but not likely a recessive yellow.
In an iris like Tropical Delight, the lycopene pink pigment is
cartenoid pigment that is prevented from becoming yellow by a set of
four recessive genes callet tangerine genes, symolized as "t" This it
is basically a repressed yellow, and in any cross where there isn't
four sets of t in seedling, the cartenoids will express as yellow.
Replicator also has yellow underlying its anthocyanin pigment. Do the
hot water test to see for yourself.
So yellow from both parents
The spot pattern comes from Replicator
Coiuld be a recessive reduction of anthocyanin, but proably not, as
prescense of anthocyanin is a dominant , and very often you get non
anthocyanin seedlings from crossing two anthocyanin parents, as some
seedlings just don't get a dosage of anthocyanin gene.

Here's an interesting one for discussion. Flowered for the first time
this morning, from breeding - Replicator x Tropical Delight
Looks like a possibly recessive yellow, with thumbspot, yellow rim and
broken colour plus rebloom.
Lots of increase. Repicator grows OK for me but Tropical Delight hardly
grows at all for me and only flowers every few years.
I know Tropical Delight is registered as having "amber yellow" stds but
to me they always look peach, or is the peach from co-_expression_ of
I'd appreciate all comments
